The recall affects nearly 700,000 products sold under brands such as Bright Starts, Ingenuity and Disney Baby. Kids2, also known as Kids II, introduced rocking thresholds in March 2012. Since then, there have been five deaths in infants "after infants have rolled uncontrollably or otherwise from their backs to the stomach".
The sleepers were sold by major retailers such as Walmart, Target and Toys "R" Us, according to the announcement by the US Consumer Product Safety Commission.
Parents should stop using the Kids2 thresholds immediately and call Kids2 toll-free at 1-866-869-7954 or www.kids2.com for a refund or voucher.
The announcement follows a similar recall from Fisher-Price Rock's Play hoses after the popular product was linked to more than 30 child deaths in 10 years. The recall involved about 4.7 million sleepers, officials said.
The American Academy of Pediatrics recommends babies sleep on a firm sleeping surface such as a crib or a basket of tight-fitting sheets on their backs. The academy also recommends avoiding soft linens as well as slouchy sleep products that have to hold back a baby.
